Authentication bypass testing involves systematically probing login flows, password resets, and MFA mechanisms to detect security flaws. This includes checking for SQL injection in login forms, predictable reset tokens, and account enumeration via timing analysis.

Multi-factor authentication bypass involves circumventing MFA challenges by exploiting session handling flaws or token generation vulnerabilities. It tests whether an attacker can skip the MFA verification step or hijack the session post-login to gain unauthorized access.

Account enumeration prevention requires testing login error messages and response timing to ensure they do not reveal whether a username exists. Authentication security audits identify these flaws by analyzing server responses during failed login attempts and password reset requests.

OAuth and SSO takeover testing detects vulnerabilities in single sign-on setups by analyzing token handling, redirect URI validation, and session management. Security audits target these integration points to identify flaws that could allow unauthorized account access.

Common session management flaws include predictable session tokens and improper session invalidation upon logout or timeout. Authentication security testing identifies these vulnerabilities by analyzing token generation patterns and verifying session boundary enforcement.

Penetration testing can detect password reset flaws by testing for predictable reset tokens, reusable tokens, and improper expiration settings. Security audits apply these techniques to identify vulnerabilities in the password recovery workflow.
